Economics, Markets, Crypto & Trading
Economics, market mechanics, crypto, trading, and risk
-
Crypto Market Structure
Crypto trades continuously across fragmented venues, each with its own prices, liquidity, custody, and rules.
-
Liquidity Is Exit Capacity
Liquidity is the ability to trade meaningful size quickly without moving price much; volume alone can be misleading.
-
Reading an Order Book
An order book lists resting buy bids and sell asks; the gap between the best prices is the spread.
-
Slippage Is an Execution Cost
Slippage is the difference between the expected price and the average executed price, often caused by thin depth or fast movement.
-
Market vs Limit Orders
A market order prioritizes execution; a limit order prioritizes price but may not fill.
-
Volatility Changes the Bet
Volatility measures variation, not direction, and it changes position risk and execution quality.
-
Leverage and Liquidations
Leverage magnifies gains and losses; when collateral falls below maintenance requirements, a venue may forcibly close the position.
-
Token Supply and Dilution
Price depends on demand relative to circulating supply, while unlocks and emissions can increase future selling pressure.
-
Market Cap vs FDV
Market cap uses circulating supply; fully diluted valuation uses the supply expected if all tokens were available.
-
On-Chain Signals Need Context
Blockchain data can show activity, fees, holders, and transfers, but labels, batching, and incentives can distort interpretation.
-
Wallet Flows Are Clues
Deposits to or withdrawals from known exchange wallets may suggest intent, but they do not prove a future trade.
-
Stablecoins Carry Risk
Stablecoins aim for stable value using reserves, overcollateralization, or algorithms; each design has depeg, issuer, liquidity, and regulatory risks.
-
BTC and ETH Play Different Roles
Bitcoin is commonly treated as a scarce monetary asset, while Ether also pays for computation and secures Ethereum; neither role guarantees value.
-
DEX vs CEX
Centralized exchanges custody assets and match orders internally; decentralized exchanges settle through smart contracts and user wallets.
-
Risk Management Before Entry
A trade plan defines invalidation, maximum loss, time horizon, and exit conditions before emotion rises.
-
Position Sizing
Position size converts a loss limit and invalidation distance into exposure.
-
Support and Resistance Are Zones
Past trading areas may influence behavior, but support and resistance are probabilistic zones, not physical barriers.
-
Momentum vs Mean Reversion
Momentum expects a move to persist; mean reversion expects deviation to shrink. Each works only under suitable regimes and horizons.
-
Correlation Concentrates Risk
Different tokens may fall together because they share liquidity, leverage, or narrative drivers.
-
Trading Biases
FOMO, loss aversion, confirmation bias, recency, and the disposition effect can override a written plan.
-
Scams and Manipulation
Guaranteed returns, urgency, impersonation, pump-and-dumps, fake airdrops, and hidden contract controls are warning signs.
-
Decision Journal, Not Predictions
A journal records information, assumptions, probabilities, execution, and outcome so process can improve independently of luck.
